The following dialog appears:<br />

Status Fields<br />

INPUT SECTION<br />

The input section displays the status of the input signal for the currently<br />

selected channel pair. Channel pairs are selected using the pop-up box in<br />

the upper left corner of the dialog box.<br />

Input Status — This indicator has five color states. Green indicates that<br />

the input is enabled and a valid, synchronous signal is present. Red<br />

indicates that the input signal is invalid or not synchronized to the Master<br />

Clock. Red crossed out indicates that the input signal is not locked and the<br />

input is muted. Yellow indicates that the input is enabled but no signal is<br />

present. Gray means that the input is disabled.<br />

CRC — CRC stands for Cyclic Redundancy Check, a method for detecting<br />

errors in a digital audio signal. CRC errors may arise from data corruption<br />

or lack of synchronization between the source and receiver. The CRC A<br />

indicator is for channel 1 of the AES input pair, and CRC B is for channel 2.<br />

Green indicates a valid input signal, red indicates CRC errors and gray<br />

indicates a lack of CRC signal.
